. MACHINE FOR PRESSING SEAMS.

Application filed April 24-,

To all whom it may concern:

Be it known that I,

ford, county of Worcester, State of Massachusetts, have invented an Improvement in Machines for Pressing Seams, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representlng like parts.

This invention relates to a device for pressing seams and has for its object to provide a'novel construction by which an ironing as well as a pressing action is produced.

The invention is capable of use for press ing various kinds of seams, but I have herein illustrated it as it might be employed for pressing the seam at the back of a shoe upper. i

I will first describe a selected embodiment of my invention and then point out the novel featuresin the appended claims.

Figure 1 is a side view of a machine embodying my invention; F1g. 2 1s a side View of said machine looking from the opposite side from that shown in Fig. 1; Fig. 3 is a top plan view; Fig. 4 is a section on the line M, Fig. 2; Fig. 5 is a perspective view showing twopieces of a ut with theseam unpressed; Fig. 7 shows ,As stated above, the machine 2 herein shown is capable of being used to press seams of a great variety illustrating one use to which the invention may be put, I would refer to the pressing of the back seam formed in the manufacture of a shoe upper.

In Fig. 5 I have illustrated two pieces 1 and 2 which may be the two sides of a shoe upper, said pieces being placed face to face and stitched together along the edge 3 by a line of stitching 4, the stitches of which pass through both of the pieces 1 and 2. After the stitch is thus formedand the two pieces 1 and 2 are opened out away from each other, as shown in Fig. 6, the seam presents arib which it is desirable in many cases to press or flatten. In myco-pending application Se. No. 93,151, filed April 24, 1916, I have illustrated and described a machine ressing a'seam such as shown in Fig. 6 an which comprisesa work-sup- Specification of Letters Patent.

to move the presser roll along the seam to be pressed thereby to separate the edges 3 and fold them down against the body of the material, said means being constructed to rotate the roll at a sufficient speed relative to its movement over the seam so that the periphery of the roll will have a sliding or ironing contact with the work in addition to itsrolling contact. The device which I have herein illustrated operates in this way, but involves a different construction from that shown in my said co-pending application.

5 indicates the frame which supports the working parts of the machine and 6 is the work-supporting member in the form of an arm having the work-sustaining edge 7 on which the work pressed is placed. This arm is shown as mounted on a stud 8 extending from the frame and as provided with a flange 9 which carries two adjusting screws 10 that bear against the portion 11 of the frame, this construction providing means for adjusting the angular position of the arm 6 slightly.

The seam-pressing roll is shown at 12 and in the present embodiment of my invention it is mounted in a swinging carrier 13 which is pivotally mounted at 14 to an arm 15 eX- tending from the portion 16 of the frame. Means are provided for swinging the arm 13 to and fro, that herein shown being a crank arm 17 fast on a shaft 18 and connected by a link 19 to the swinging carrier 13. The shaft 18 may be driven in any suitable way. I have herein shown for this purpose a gear 20 which may be clutched to the shaft and which meshes with and is driven by a pinion 21 on a driving shaft 22 that is driven from a driving pulley 23. Any suitable means may be provided for clutching the gear 20 to or unclutching it from the shaft 18. I will preferably use for this purpose a clutch mechanism shown. generally at 24 which is of the one-revolution type so that when it is engaged thereby to clutch the gear 20 to the shaft, it will become automatically unclutched when the gear 20 has made one complete revolution. Inasmuch as any of the various well-known types of one-revolution clutches might be used, I do not think itis necessary to illustrate any particular detailed construction herein. 25 indicates the lever by which the clutch is thrown into operations Inasmuch as the carrier 13 swings about a fixed center 14 as a pivot, I propose to so mount the presser wheel 12 in the carrier that said wheel may move vertically therein and thus follow the edge 7 of the work-supporting arm. To provide for this the carrier 13 is formed with the guiding slot 26 extending longitudinally thereof and in said slot 1s reciprocably mounted a slide 27 carrying a stud 28 at its lower end on which the roll 12 is mounted. Means are provided for positively rotating the roll 12 as it is moved bodily longitudinally of the work-supporting arm 6. In the present embodiment, such means comprises a gear 29 rigid with the presser roll 12 and which meshes with an intermediate gear 30 journaled on a stud 31 carried in the slide 27, said intermediate gear in turn meshing with a segmental gear 32 that is mounted on a stud 33 carried in said slide 27. The gear 32 is oscillated positively during the swinging movement of the gear 13 thereby to transmit rotary motion to the presser wheel 12, and the relative proportion of the gears 32, 30 and 29 is such that the speed at which the roll 12 is rotated about its axis due to the movement of the gear 32 is faster than that which results simply from the rolling contact of the roll on the edge 7. There will, therefore, be a slipping contact between the roll 12 and the work as well as the rolling contact. For thus positively oscillating the segmental gear 32', I have provided an arm 34 which is rigid with the gear and which is pivotally connected to one end of a link 35, the other end of which is pivotally connected to the frame at 36.

Means are also provided for holding the roll 12 yieldingly in engagement with the edge 7, as the carriage 13 oscillates about its pivot. For this purpose I have provided a spring 56 which bears on an arm 37 that is pivoted to the frame at 38, said arm having a roll 39 at its end that engages a cam surface 40 formed on the link 35. The upper end of thespring 36 is received in a cap or housing 11 which is backed by an adjusting screw 42 that is adjustably mounted in an ear or projection 13 extending from the arm 15 of the frame. The adjusting screw 42 provides means for varying the tension of the spring 56 and the consequent pressure of the member 37 against the link 35. The roll 12 is thus yieldingly held against the work which is sustained on the work support.

In the particular embodiment of the invention herein shown, the work-sustaining edge 7 is made with convex and concave portions, this particular shape being de signed to fit the back seam of a shoe upper. It will be understood, however, that the particular shape of the edge 7 will depend upon the shape and character of the seam which is to be pressed. Further, the shape of the cam surface 40 may be varied, depending somewhat upon the shape of the work-sustaining edge 7 and upon the pressure which t is desired to apply to the seam at various points along its length.

In using the device herein shown for pressing a seam, such as shown in Figs. 5, 6 and 7, the seam to be pressed is placed over the edge 7 with the edges 3 projecting upwardly therefrom, and the machine is then set in operation. The movement of the roll 12 over the seam will part the two edges 3 and fold them down against the body of the pieces 1 and2, and during this movement, the roll not only performs the pressing action, but because of the fact that it is positively driven at a speed greater than that which would result from the rolling contact of the roll with the work, an ironing action will be produced which will smooth the pressed seam.
